The game is Dummy Defense. It launched yesterday and is currently at #41 top overall in the US app store. I did some heavy promotion yesterday with a large email list, and FreeAppADay is promoting my other app, SimplePhysics, which is driving quite a few sales. I'd be glad to hear your feedback about the game as well as answer any questions regarding the development or marketing efforts.Here's the trailer:
